Robotic Physiotherapy and Rehabilitation: Who Benefits and How It Works
Robotic rehabilitation is device-assisted physiotherapy that allows walking and arm–hand movements to be practised with many regular, measurable repetitions. This page brings together what it is, who may benefit, what a session looks like and its limits.
What robotic rehabilitation is
Robotic devices help move the arm or leg, provide support where needed and record performance. The aim is to safely increase the intensive, task-oriented repetition the brain needs to relearn movement (neuroplasticity). Robotic therapy does not replace the physiotherapist. It is part of a programme the physiotherapist leads.

Gait robots
These include exoskeleton systems that guide leg movements on a body-weight-supported treadmill, and end-effector (footplate) devices. According to a Cochrane review, adding electromechanical or robotic gait training to physiotherapy after stroke increases the likelihood of walking independently. The effect is most evident in the first 3 months and in patients unable to walk at the start [1].
Arm–hand robots
These train shoulder, elbow, wrist and finger movements through game-like tasks. A Cochrane review reports that robot-assisted arm training may improve activities of daily living, arm function and muscle strength, with low- to moderate-quality evidence [2].
Who may benefit
- People after stroke or brain haemorrhage (Stroke guide)
- Traumatic and other acquired brain injury (Brain injury guide)
- Spinal cord injury, especially partial (incomplete) injury [3] (Walking after spinal cord injury)
- Some neurological diseases, such as Guillain-Barré syndrome and multiple sclerosis
Suitability is assessed by the physician, based on cardiovascular status, joint range of motion, bone health, skin condition, body size and the patient’s ability to take part.
Robot plus therapist: the hybrid approach
Guidelines state that robot-assisted gait training may be considered alongside conventional therapy for patients who cannot walk [4]. For the best results, robotic sessions are combined with conventional work on balance, strength, real-world walking and daily activities, and the programme is updated with regular measurements.
What a session looks like
- Assessment by the physician and physiotherapist, and goal setting
- Fitting the device to the patient’s measurements
- Typically 30–60 minutes of practice, with support and speed adjusted step by step
- Progress tracked with device data and clinical measures
Limits and realistic expectations
Robotic therapy is not a stand-alone cure. Its effect depends on the patient’s condition, timing, therapy intensity and integration with other therapies. In mildly affected patients who already walk, the added benefit over conventional gait training may be limited [1].
Who decides on suitability
Whether robotic or other advanced therapies are suitable is decided by a physical medicine and rehabilitation (PM&R) specialist focused on neurorehabilitation, after examining strength, spasticity (muscle stiffness), joint range, balance, cognition, skin condition and general health. Prof. Dr. Engin Çakar works in this field and can be consulted online or in person; otherwise, consult a PM&R specialist near you. The training itself is carried out by your physical medicine and rehabilitation specialist and the physiotherapist together, with settings adjusted as the person improves.
Possible reasons to postpone or avoid robotic training
- Unhealed fractures, severe osteoporosis (bone thinning) or unstable joints
- Pressure sores or skin problems where the device straps sit
- Uncontrolled blood pressure or heart problems
- Fixed joint contractures (shortening that limits movement) that prevent correct alignment
- Body size outside the device limits
What families can do
- Ask how robotic sessions fit into the overall plan and which goals they target.
- Practise the transferred skills at home, such as standing, stepping or reaching, as instructed.
- Report skin redness, pain or unusual fatigue after sessions.
When to consult your PM&R specialist
Consult a PM&R specialist before starting robotic therapy, if progress stalls, or if new pain, swelling or skin problems appear.
Frequently asked questions
Can everyone have robotic physiotherapy? No. Suitability is determined by medical examination and device criteria.
Is robotic therapy better than conventional physiotherapy? It is not an alternative to conventional therapy. Combined with it, it may add benefit, particularly in severely affected patients.
How many sessions are needed? The number of sessions is planned individually according to the condition, goals and progress.
Is robotic gait training painful? It is generally not painful. The device is adjusted to the patient’s size and tolerance.
Can robotic training be done at home? Most systems are used in rehabilitation centres. Some simpler devices exist for home use, but their suitability should be assessed individually.
How many sessions are needed? This varies with the condition, goals and response. Progress is reviewed regularly rather than fixed in advance.
